Mapping Spatial Variations in Fatal Overdose Risk in BC

The overdose crisis is more complicated than ever as the risk distribution is now affected by interventions in addition to the endogenous factors. We used a spatial modelling approach to estimate fatal overdose risk per event, with covariate adjustments at the individual level. We found the odds of fatal overdose in some regions were 50% higher than in others. Temporal variations (2015 - 2018) in fatal risks were also modelled, and we observed an increasing trend over the entire province. However, risk in the Interior and Northern BC increased earlier and faster, suggesting that these regions may lack harm reduction services to counteract the province-wide increasing illicit drug toxicity.
